Hybrid energy system mimics processes in photosynthesis (2014-06-01 16:21:41)
Artificially replicating the biological process of photosynthesis is a goal being sought on many fronts, and it promises to one day improve light-to-energy efficiencies of solar collection well beyond what's possible with photovoltaic cells. One of the first steps on the road to achieving this objective is to imitate the mechanisms at work in the transfer of energy from reception through to output. Next view
Scientists create weavable Li-ion fiber battery yarn (2014-05-31 11:15:06)
Scientists at the Fudan University in Shanghai, China, have developed a high-performance Li-ion battery made of carbon nanotube fiber yarns. Roughly one 1 mm in diameter, the fiber shaped lithium-ion batteries are reported lightweight enough to create weavable and wearable textile batteries that could power various devices. The researchers say that the yarn is capable of delivering nearly 71 mAh/g of power, and can also be woven into existing textiles to create novel electronic fabrics. Next view
Could this little-known biomass generator start an energy revolution? (2014-05-30 17:50:01)
It could be the most important portable power plant you've never heard of. It's called the "Power Pallet" and it is essentially a combined biomass refinery and generator that fits on a single pallet and can kick out up to 20 kilowatts of electricity. Next view
Structural supercapacitors could make batteries and power cords obsolete (2014-05-30 17:41:31)
Imagine using a mobile phone powered entirely by its casing, or an electric car that runs off power stored in its chassis. Researchers at Vanderbilt University have created a structural supercapacitor that could, they believe, bring this closer to reality, making batteries and power cords obsolete. The structural supercapacitor could make it possible to store energy directly in structural materials, allowing them to deliver power long-term while surviving the real-life mechanical stresses they're bound to experience.

Aircraft fuel consumption can be reduced by 15 per cent (2014-05-30 15:36:34)
Two aircraft engine concepts, geared turbofan and open rotor, can enable a significant reduction to aircraft fuel consumption. With open rotor, the potential reduction is 15 per cent. These are the findings of Linda Larsson at Chalmers University of Technology, who has analysed and evaluated the two concepts. Next view
Scientists develop new hybrid energy transfer system (2014-05-29 15:39:12)
Scientists from the University of Southampton, in collaboration with the Universities of Sheffield and Crete, have developed a new hybrid energy transfer system, which mimics the processes responsible for photosynthesis. Next view
'Home-made' electricity creating buzz in Germany (2014-05-29 15:16:11)
Klaus Meier lists three reasons for generating his own electricity in his family hotel in Germany's southern city of Freiburg—"cost savings, energy efficiency, climate protection". Next view
New record efficiency for quantum-dot photovoltaics (2014-05-29 10:33:15)
Flexible, inexpensive, large-area, lightweight solar cells are difficult to produce as they require an inert atmosphere and high temperatures, and they often degrade in a short time after exposure to air. Researchers at MIT, however, have used a new method to craft solar cells from ultra-thin layers of quantum dots in a process that promises to avoid these problems, and at room temperature. At the same time, they have also set a new record of nine percent for the most efficient quantum-dot solar cells produced to date. Next view
New "dual carbon" battery charges 20 times faster than Li-ion (2014-05-20 15:20:16)
Japanese company Power Japan Plus has announced the development and planned mass-production of "Ryden," a disruptive carbon battery that can be charged 20 times faster than an ordinary lithium-ion cell. The battery, which is cheap to manufacture, safe, and environmentally friendly, could be ideal to improve the range and charging times of electric cars. Next view
Seatower's game-changing wind turbine foundations could reduce the cost of offshore wind farming (2014-05-16 17:01:11)
Offshore wind farming combines the clean, green, environmentally neutral benefits of land-based wind turbines, while being a lot less visually intrusive ... and restricting the usual NIMBY opposition to crustaceans and invertebrates. It's currently a lot more expensive to install turbines out at sea, though, and that's restricting the sector's development. Which is why the Seatower Cranefree turbine platform could be such a significant step forward. Cheaper and easier to install, and requiring less gargantuan and specialized equipment than standard monopile foundations, the Seatower base could help offshore wind farms reach profitability a lot quicker.
